Letters Patent No. 98,222, `dated December 28, 1869.

The Schedule referred to in these Letters Patent and. making part of the same.

To all whom z't may concern l Be it known thatI, JOHN BOURNE, of N o. 1 Northumberland Terrace, Regents Park Road, in the county of Middlesex', England, have invented a new and use- .ful Improvement in Auxilary`Propulsion of Vessels;

andI do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part oi' this specification.

My invention relates to the propulsion of vessels by means of oars opera-ted by mechanism, which will be hereinafter described.-

The use of oars, moved by a steam-engineset within the vessel, has been proposed,I but such an arrangement virtually converts ther vessel into a steamer, and the special advantages of 1the application are thereby lost.

In my arrangement, the oars are nroved'by any suitable power applied on the deck of the vessel, which may be the force of men at a winch-handle, or other suitablepurichase, or it may*be a steam-engine or engines, such as those employed to .give motion to the winches for hoisting the cargo and pumping the ship,

while the steam maybe condensed into ii'esh water for drinking-purposes. There is thus no'jnterfereuce with the holds, which remain intact as infcommon sailing-shi ps. The oars are suspended from. the sides, and they are made capable of bcing easily 4liftedl out of the water when not required. The manuel' in which I carry my invention into effeet, is shown in the accompanying sheets of drawings- Figure 1, Sheet I, being a planer top view of a portion of the deck of a ship, showing one oar in place, and the means of working it connected therewith.

Figure 2, Sheet Il', is apart-iai transverse vertical section of the ship, showing also the 'manner of applying steam-power to the working of thel propeller.

standards L, projecting from the deck the vessel.

1n fig. 1, I have shown a winclr-handle; a, app-lied" The oars I are carried by brackets ,G G, hung to the sides of the ship, or, in lieu thereof, swivellingcranes may be employed. These brackets G G, when not iu use, maybe lifted otitheir supports-id, and stowedaway, or when 'hung as cranes, they maybe swung out of the way against the sides of the vessel.

The oar-shank is ,fitted through altube, F, which has projecting trunnions c c, that have their bearings in the bracket G. A'shoulder, g, on the shank of each oar, suspends the same from the said tube Ii. The oar is thus swivelled'in the tube, and cau turn rn the same, to be feathered, and swing with the same on the trunnionst7 c, to he worked toward and away from the ship.

The rod B iscmmeGtedwit-h, that is, pivoted to the upper 'end of checar-shank, and works the oar to'and ti'om.the`si de of the ship, while the other coune'ctingrod11%,',l derivingits.-motion from the crank c, 'works a short handle ortiller, E, which projects from the upper part ofthe 'oarshank, and swings the latter therefore on its own axis.

The throw otl the two cranks, b c, is the same, but one being vseta. certain distance in advance ofthe other,

@it follows vth'atwhenboth are in action, a scullingmotion is imparted tothe oar, oueot' the cranks irnpeiliirg theoarfand the other feather-ing it. i

`TheA same engine which works the oars may be made to work the winchesat the several hatchways,

-by means 'of pitch-chains, 0r a steam-winch, with two cylinders ofthe usual construction, may be employed for this purpose, and also for giving motion tothe oars.

In fig. 2, Sheet 1I, the position of the cranks, rela. vtively with one another, is. shown at b c, B Bf being the connecting-rods, as before, one of which is pivoted to'pins D, projecting from the top ofthe oar, and the other, by pins f, to the short feathering'-arm or tiller E.

l is the fulcrum-sleeve, on which the oar oscillates,'

and in which it turns.

The oar-'shank is fitted through .this short tube or cylindrical socket I, and is supported upon the edge ofthe socket by the collar or shoulder g, as aforesaid.

The fulcrurn-sleeve is carried by the bracket G, which is braced by rodsH, to keep it in position when the oar is in use. The blade of the,oar is shown at I, and a chain or rope may be atiixed thereto atA the point K, to take the forward thrust, and also' to assist in hauling the oar out ofthe water when it is no longer required.

The oar-shank may also be provided with a slide, M, guided iu the lower :part ofthebracket G.

When an engine is employed, the engine-shaft is fitted with a pinion, which gears into a large spur'- wlreel on the crank-chat't, connected with the oars..

This arrangement will enable' the engine to work at nEeENT-s PARK intended to be imparted to the ship.

within the ship, such application havingr been before chiuery which is only to give an occasional benefit.,

its proper speed while the oars move only at the slow speed which is proper for the small amount of speed proposed, but involves thes'rious objection of perfurating the sides, and of occupying 'the hold with ma.-

and has the further defect of offering difficulties in de'- l-acbing and raising,r ont',V of' the water the oars when not required for use; bul;

1 claim as new, and desire t-o secure by Letters Patent` l Y 1. The oar I, provided with the pivoted sleeve F,

were

in combination with the bracket @geraak EfrodsB and B', and crank-shaft b c, when said parts are arranged, with-relation 'to the deck and stern of the vessel, and to operate as-shown and described.

2. The Vpivoted sleeve F and slide M, n combination with the removable bracket Gand oar I, provided with collars, and all constructed and arranged as shown and described.

3. 'lbe bracket G, arrange-d ou the side of a ship, so as to be easily reluoyed or swung out; of the way, and for the purpose of sustaining an oar or oars to be operated by machinery for propelling vessels in calms, as set forth.

my invention signed by 1868. JOHN BOURNE.
